CORN-SHELLER.

SPECIFICATION forming part of Letters Patent No. 583,542, dated June 1,1897. Application filed December 10, 1896. derial No. 615,144. (Nomodel.)

To all whom, it may concern:

Be it known that I, GEORGE W. NELSON, a citizen of the United States,residing at Five Forks, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements inOorn-Shellers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in the construction ofcorn-shellers, and the ob.- ject is to provide an effective and reliabledevice of this kind; and to this end the novelty consists in theconstruction, combination, and arrangement of the same, as will behereinafter more fully described, and particularly pointed out in theclaims.

In the accompanying drawings the same reference-numerals indicate thesame parts of the invention.

Figure 1 is a side elevation of my improved corn-sheller. Fig. 2 is alongitudinal section of the same. Fig. 3 is a top plan view, and Fig. 1is a transverse section of the same.

1 1 represent suitable standards provided with the usual longitudinaland cross braces 2 3, all of which constitute the frame of the machine.

3 3 represent the sides, and 4 the front end. 5 is the inclinedreticulated bottom, secured to the sides and extendingfrom the front endto within a few inches of the lower end, leaving a space or opening 6for the passage of the shelled corn.

7 and 8 represent two spirally-fluted shafts extending parallel witheach other a short distance above the inclined bottom, their lower endsbeing journaled in bearings in a cross-brace 9 and their upper or frontends journaled in .and extending through the front end 4:, where each isprovided with a beveled gear 10.

12 12 represent brackets secured to the front end of the machine, inwhich is journaled a transverse shaft 13, provided with a hand-Wheel 14at one end, and on the other end is fixed a disk 15.

16 represents a two-faced beveled gearwheel, the oppositely-disposedteeth of which mesh with and simultaneously rotate the gear-wheels 10 inopposite directions, which causes the contiguous parallel peripheries ofthe spirally-fluted shafts 7 and 8 to turn inwardly toward each other.

The continuous flanges 1'7 of the shafts 7 and 8 are provided with aseries of regularlydisposed V-shaped notches 18, the remaining solidportion of the periphery of the flange constituting a series of teeth19.

A central longitudinal rib 20 extends between the lower edges'of theshafts 7 and 8, and its upper face is provided with a series offorwardly-inclined shelling-teeth 21.

22 represents a shaking-pan centrally pivot-ed on a stud 23 in ahorizontal arm 24 at the rear of the machine. This pan receives the cobas it is discharged from the machine, and its upper face is providedwith a series of picker-teeth 25, which remove any loose grains adheringto the cob and allow them to drop through the orifices 26 in the pan,where they fall on an inclined shelf (not shown) and thence back intothe receptacle under the discharge-opening 6. This pan 22 is providedwith an eyebolt 28, fixed at one end thereof, to which is connected arod 29, extending to a stud 30 on the outer face of the disk 15, whichimparts a shaking motion to said pan when the driving-shaft 13 isrotated.

31 31 represent retarding-shoes mounted on rock-shafts 32 32, journaledin the brackets 33 33, secured to the upper edge of the sides 3 3, saidshoes being adjustably held at an angle to the axis of thespirally-fluted shafts 7 and 8 by finger-springs 34, secured to thecross-bars 35 35, and the tension of these springs may be increased ordiminished by the regulating-screws 36. The lower face of theseretarding-shoes 31 31 is concave in cross-section, and these concave'faces are provided with a series of longitudinal parallel bars 3'7,formed with rearwardly-inclined teeth 38, which serve the double purposeof pressing the ear of corn into intimate contact with thespirally-flanged shafts 7 and 8 and r at the same time assisting in theoperation of removing the grains from the cob.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such IOO . tive connection with both thegears 10 10, in

combination with the central longitudinal toothed rib 20, and thepivoted retardingshoes 31 having their concave faces provided with aseries of longitudinal parallel toothed bars 37, substantially as shownand described.

2. A corn-sheller, comprising the inclined spirally-flanged parallelshafts 7 and 8, formed with V-shaped teeth 19, the bevel gear-Wheels 1O1O fixed on the contiguous upper ends of said shafts, and the transverseshaft 13 carryin g the two-faced bevel gear-Wheel 16, meshing with thegear-Wheels 10 10, and provided with the disk 15, in combination withthe central longitudinal toothed rib 20, arranged parallel with andbetween said shafts 7 and S, the pivoted shaking'pan 22, formed with theorifices 26 and vertical picker-teeth 25, and connected at one end tothe disk 15 by a rod 29, the retarding'shoes 31 fixed on the rock-shafts32 journaled in brackets 33, and the adjustable finger-springs 34, theirfree ends bearing on the lower end of the shoes 31, substantially as andfor the purpose set forth.

In testimony whereof I hereunto aflix my signature in presence of twoWitnesses.

GEORGE \V. NELSON.
